PLOW.

Specification of Letters Patent.

Patented Apr. 10, 191'?.

Application filed March 24, 1914. Serial No. 826,945.

To all whom t may concern:

Be it known that l, LEE O. Bono, a citizen of the United States, residing at Fresno, 1n

the county of Fresno and State of California, have invented new and useful Improvements in Plows, of which the following is a specification.

This invention relates to plows, and it has for its obj ect to provide simple and effective means whereby the beam may be vertically adjusted in order that by such adjustment the depth of the furrow may be regulated without resorting to gage wheels, adjusting clevises or other expensive and cumbersome means for tilting the beam to eect a similar result.

The invention consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and claimed, reference being had to the accompanying drawing, in which,-

Figure 1 is a side elevation partly in section of a plow constructed in accordance with the invention.

Fig. 2 is a top plan View.

Corresponding parts in both gures of the drawing are denoted byclike characters of reference.

The beam 15 which may be either a wooden or a metallic beam is provided with a vertical bore 16 for the Apassage of a threaded stem or shank 17 at the upper end of the standard 18 with which the mold board 19 and land-side 20 are connected in the customary manner. The threaded shank 17 is provided with nuts 21, 22, respectively, above and below the beam, and by proper manipulation of which vertical adjustment of the beam may be readily effected.

Handles 23 have been shown as being connected in any well known manner with the mold board and the land-side, said handles being connected together and spaced apart by a cross bar 24 having a socket 25 in which'the lower end of an adjusting screw 26 is swiveled, said adjusting screw being threaded through the rear portion of the beam and provided at its upper end with a wrench seat 27, whereby it may be rotated, thus effecting a rm connection between the rear end of the beam and the cross bar connecting the handles so that the beam will be strongly reinforced and at the same time permitting the beam to be moved up or down, as may be required, without necessity for tilting. The cross bar 241 is provided with downturned ears or lugs 28 for the passage of pivot members 29 whereby it is connected with the handles 23. rlhus, when the beam 15 is adjusted vertically with respect to the threaded shank of the standard, the cross bar will be capable of tilting slightly so that the adjustment of the beam will not be obstructed. It will be readily seen that assum ing the draft to be exercised in a predetermined horizontal plane, upward or downward adjustment of the beam will cause the pull to be exercised more or less in a downward or an upward direction, as the case may be, thus gaging the depth of the cut.

Having thus described the invention, what is claimed as new, is

In a device of the class described, in combination, a plow beam, a pair of connected handles having a cross bar secured between themat their lower ends and horizontally disposed said cross bar being formed with a socket, an adjusting screw having a head adapted to turn in said socket in a horizontal plane and positioning said screw vertically, said beamhaving a threaded opening in which said screw is threaded, a head formed upon the outer end of said screw, a plow standard secured to said handle and provided with a vertically disposed threaded shank, said beam having an unthreaded opening through which said shank projects, and aA pair of nuts threaded upon said threaded shank and clamped upon the upper and lower edges of said beam to position said beam horizontally, said screw being held against displacement from said socket.

In testimony whereof I aiiiX my signature in presence of two witnesses.

LEE O. BOBO.
